Abstract

Abstract In a camera adapted to function with stored data, the exposure time data, aperture value data and override data are stored and the stored aperture value data is normally indicated with provision for indication of the stored override data in place of the aperture value data. The stored exposure time data may be indicated by additional indicating means which can be disabled while the stored override data is being indicated.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 83 words
A camera adapted to function with stored data, comprising: first means for storing exposure time data; second means for storing aperture value data; third means for storing override data; first means for normally indicating the stored aperture value data and also capable of indicating the stored override data in place of the aperture value data; second means for indicating the stored exposure time data; and means for disabling said second indicating means while said first indicating means is indicating the stored override data.
Claim 2
Dependent Claim 83 words
A camera adapted to function with stored data, comprising: first means for storing exposure time data; second means for storing aperture value data; third means for storing override data; first means for normally indicating the stored aperture value data and also capable of indicating the stored override data in place of the aperture value data; second means for indicating the stored exposure time data; and means for disabling said second indicating means while said first indicating means is indicating the stored override data.
Claim 3
Dependent Claim 102 words
A camera adapted to function with stored data, comprising: first means for outputting exposure time data; second means for outputtig aperture value data; third meand for outputting override data; first means for normally indicating the aperture value data output by the aperture value data outputting means, and also capable of indicating the override data output by the override data outputting means in place of the aperture value data; second means for indicating the exposure time data output by the exposure time data outputting means; and means for disabling said second indicating means while said first indicating means is indicating the override data.
Claim 4
Dependent Claim 102 words
A camera adapted to function with stored data, comprising: first means for outputting exposure time data; second means for outputtig aperture value data; third meand for outputting override data; first means for normally indicating the aperture value data output by the aperture value data outputting means, and also capable of indicating the override data output by the override data outputting means in place of the aperture value data; second means for indicating the exposure time data output by the exposure time data outputting means; and means for disabling said second indicating means while said first indicating means is indicating the override data.
Claim 5
Dependent Claim 178 words
A camera adapted to function with override data, comprising: means for introducing override data, including: first means responsive to a manual operation for setting desired override data; second means responsive to a manual opertion for setting aperture value data; first means for alternatively indicating one of the override data or the aperture value data; second means for indicating additional data relating to exposure; and means responsive to said first setting means for controlling said first and second indicating means, including: means for selecting the override data to appear at said first indicating means when said first setting means is manually operated; means for selecting the aperture value data to appear at said first indicating means when said first setting means is not manually operated; and means for disabling said second indicating means so that override data appears without appearance of the additional data when said first setting means is manually operated, and for enabling said second indicating means so that the additional data appears with the aperture value data when said first setting means is not manually operated.
Claim 6
Dependent Claim 178 words
A camera adapted to function with override data, comprising: means for introducing override data, including: first means responsive to a manual operation for setting desired override data; second means responsive to a manual opertion for setting aperture value data; first means for alternatively indicating one of the override data or the aperture value data; second means for indicating additional data relating to exposure; and means responsive to said first setting means for controlling said first and second indicating means, including: means for selecting the override data to appear at said first indicating means when said first setting means is manually operated; means for selecting the aperture value data to appear at said first indicating means when said first setting means is not manually operated; and means for disabling said second indicating means so that override data appears without appearance of the additional data when said first setting means is manually operated, and for enabling said second indicating means so that the additional data appears with the aperture value data when said first setting means is not manually operated.
Claim 7
Dependent Claim 16 words
A camera as claimed in claim 3, wherein the additional data is the exposure time data.
Claim 8
Dependent Claim 131 words
A camera adapted to function with override data, comprising: first means for storing override data; second means for storing aperture value data; first means for normally indicating the override data, and also capable of indicating the aperture value data in place of the override data; second means for indicating additional data relating to exposure; a manually operable member; and means responsive to said manually operable member for controlling said first and second indicating means, including: means for switching said first indicating means to indicate the override data in place of the aperture value data while said manually operable member is operated and for allowing said second indicating means to indicate the additional data with the aperture value data indicated at said first indicating means when said manually operable member is operated.
Claim 9
Dependent Claim 131 words
A camera adapted to function with override data, comprising: first means for storing override data; second means for storing aperture value data; first means for normally indicating the override data, and also capable of indicating the aperture value data in place of the override data; second means for indicating additional data relating to exposure; a manually operable member; and means responsive to said manually operable member for controlling said first and second indicating means, including: means for switching said first indicating means to indicate the override data in place of the aperture value data while said manually operable member is operated and for allowing said second indicating means to indicate the additional data with the aperture value data indicated at said first indicating means when said manually operable member is operated.
Claim 10
Dependent Claim 16 words
A camera as claimed in claim 5, wherein the additional data is the exposure time data.
